摘要： A valve for connection to the boom of a crop spraying aircraft for emission of chemicals includes a pressure actuated valve member disposed therein in order to provide positive flow of the chemicals when pumped through the valve and positive dripless turnoff when the pressure is removed from the chemicals. Further, the valve is produced in two pivotally connected sections having a gauge disposed thereon for controlling the spray angle of the emitted chemicals and to thereby adjust the swath covered at each pass.

摘要： The main storage hopper of an aerial crop dusting apparatus incorporated in aircraft is equipped with a suction pipe which extends from the outlet to the lowest depths of the hopper to insure that all the insecticide stored therein is dispensed. The suction pipe has a constant cross-sectional area throughout its length to insure constant fluid flow. The pipe attaches to the outlet by a connector which has a free bevelled edge to contact a bevelled edge of the pipe. A nut is positioned over a flange on the pipe and has threads which connect with cooperating threads on the connector to force the bevelled edges into tight communication.
摘要翻译：装在飞机上的高空作业除尘装置的主存储料斗配备有从出口到料斗的最低深度延伸的吸管，以确保其中储存的所有杀虫剂都被分配。吸管在其整个长度上具有恒定的横截面积，以确保恒定的流体流动。管子通过连接器连接到出口，连接器具有自由斜边以接触管道的倾斜边缘。螺母位于管道上的法兰上方，并具有与连接器上的协作螺纹连接的螺纹，以强制斜切边缘紧密连接。
